Cook, freeze, heat and eat with these revolutionary food containers from MasterClass. Made of robust, hygienic stainless steel, they do everything plastic containers do, and a whole lot more. They're freezer safe, oven safe even microwave safe. Yes, that's right, it's stainless steel and can be used in the microwave using proprietary technology, so it's easy to freeze and reheat leftovers, pre-prepped ingredients and prepared meals. Each container comes with an airtight, leakproof lid, complete with a pop-off steam vent for fuss-free microwaving. A great alternative to both plastic and glass containers, our all-in-one dishes are great for lunches out and about too. They're available in six sizes, ranging from snack sized (500ml) to jumbo sized (2.7 litres), and can stack up with one another to save space in storage. MasterClass is made up of foodies, thinkers, techies, do-ers and dreamers. We come together for one very good reason: to create simple, innovative products that are built to last a lifetime. You can boil it all down to one phrase: Buy Once, Buy Smart. That's in the DNA of everything we do, from our problem-solving kitchen tools to our better living solutions. It's all about making a difference, to our customers, consumers, and the world we live in. MasterClass Food Storage Container with Lid 750ml Microwave Safe in Grey
